Orthoboric acid, $H X_{3} BO X_{3}$ , behaves in water as a

Aweak dibasic Bronsted acid
Bstrong monobasic Lewis base
Cweak monobasic Lewis acid
Dstrong tribasic Bronsted acid

Answer: C

Boric acid does not release a proton itself; it accepts

OH X^{-}

from water:

B (OH) X_{3} + 2 H X_{2} O [B (OH) X_{4}] X^{-} + H X_{3} O X^{+}

. It is therefore a weak, monobasic Lewis acid.
